CPAP – What Is It?

Published by:

CPAP or Fixed Positive Airway Pressure is a mode of synthetic ventilation of the lungs with the creation of constructive pressure in the airways after exhalation. Currently, CPAP-remedy is used for the remedy of snoring, sleep apnea therapy, arterial hypertension, cardiovascular ailments, daytime sleepiness, weight problems, impotence, insomnia, and depression. How can CPAP-therapy remedy so many ailments? It’s believed that each one of those ailments are carefully related to a disturbance of normal sleep.

Why is Sleep so Necessary?

Sleep helps the body to loosen up from the stress with which an individual is confronted each day. During sleep, hormonal regulation occurs in our body. Some hormones secrete only during sleep, and some hormones secrete only after sleep. Due to this fact, if sleep is impaired, it leads to a disturbance of the hormonal balance and nervous system transmitters, which in the end causes the development of assorted psychological and physical diseases. The principle cause of disturbance of normal sleep is sleep apnea.

Sleep apnea is an absence of pulmonary air flow throughout sleep for more than 10 seconds, which is characterised by reducing of oxygen saturation within the blood (SaO2) by 4% or more. Normally, sleep apnea lasts for 20-30 seconds, nevertheless, in severe cases it could possibly last for two-three minutes. The number of episodes of sleep apnea may typically be up to 60% of the total nighttime Sleep apnea devices. Regular sleep apnea (normally not less than 10-15 occasions within an hour) is called obstructive sleep apnea syndrome. The main symptoms of the obstructive sleep apnea syndrome are daytime sleepiness, deterioration of memory and intelligence affecting capacity to work and a relentless sense of fatigue.

The principle cause of obstructive sleep apnea syndrome is an obstruction of the upper airways. Obstruction of the upper airways signifies that air cannot get into the lungs and there’s oxygen deprivation of the whole organism.

CPAP – Why is it Used?

Constant optimistic airway pressure (CPAP) is an efficient methodology of treating obstructive sleep apnea syndrome. CPAP-remedy was launched to clinical practice in 1981 by an Australian doctor and Professor. Colin Sullivan for the therapy of obstructive sleep apnea syndrome.

The mechanism of motion of the CPAP machine is kind of simple. A small compressor is used for creating constant air move below a sure pressure in the airways throughout exhalation through a flexible tube and a nostril mask. It is usually used a humidifier that gives moisturizing and heats the air which enters the airways. This gadget does not enable the upper airways to be obstructed because of the fixed constructive air pressure and eliminates the main cause of the obstructive sleep apnea syndrome.

CPAP-remedy for sufferers with obstructive sleep apnea syndrome is now universally accepted. Earlier than prescribing CPAP-remedy, a Polysomnography is required or in different words a Sleep Study. Polysomnography is a medical examination of a affected person’s sleep with the usage of specialized laptop systems. Polysomnography permits calculating the apnea index and determining the severity of the disease.

The apnea index is the frequency of apnea episodes during one hour of sleep. Apnea index determines the severity of the obstructive sleep apnea syndrome. The apnea index is considered pathologically significant if there are more than 20 apnea episodes per hour, regardless of the presence or absence of scientific symptoms. By the best way, even more than 5 assaults of sleep apnea episodes are considered to be threatening for an individual with a gradual development of daytime drowsiness, memory impairment, psycho-emotional issues, insomnia, development of cardiovascular diseases (arterial hypertension, coronary coronary heart disease or stroke), and disturbance of cardiac rhythm.

CPAP – How is it Used?

The first session of CPAP-therapy is carried out on the next night after a diagnostic polysomnography. The aim of the primary CPAP session is to pick out the minimum air pressure that eliminates obstructive apnea, loud night breathing and other respiratory disturbances in all positions of the body and in all phases of sleep. During the first session of CPAP-remedy, the minimal set of parameters might be recorded: electroencephalography, electrooculography, electromyography, chest and belly movements, body position, loud night breathing, electrocardiography, blood saturation. These parameters let you determine the work of the mind and the stage of sleep, which excludes the possibility of inadequate air pressure by means of undiagnosed wakefulness episodes.

The “golden rule” is to make use of CPAP machine every night throughout your complete time of sleep. Sufferers often follow this recommendation in severe forms of obstructive sleep apnea. In this case, there may be an improvement within the quality of sleep and daytime activity. Within the mild and moderate types of the disease, the irritating effect of the masks and airflow may sometimes decrease the standard of sleep, nevertheless, there is a clear positive impact on daytime exercise and on a number of different symptoms. One of the essential advantages of CPAP-therapy is the absence of side effects.
